Consistently Large Cosmic Flows on Scales of 100 Mpc/h: a Challenge for the Standard LCDM Cosmology
Richard Watkins, Hume A. Feldman, Michael J. Hudson
Peculiar velocity surveys have non-uniform spatial distributions of tracers, so that the bulk flow estimated from them does not correspond to that of a simple volume such as a sphe…
Cosmic Flows on 100 Mpc/h scales
Hume A. Feldman, Michael J. Hudson, Richard Watkins
To study galactic motions on the largest available scales, we require bulk flow moments whose window functions have as narrow a peak as possible and having as small an amplitude as…
Companions to Isolated Elliptical Galaxies: Revisiting the Bothun-Sullivan Sample
Barry F. Madore, Wendy L. Freedman, Gregory D. Bothun
(Abridged) We investigate the number of physical companion galaxies for a sample of relatively isolated elliptical galaxies. NED has been used to reinvestigate the incidence of sat…
Bulk Flow and Shear Moments of the SFI++ Survey
Hume A. Feldman, Richard Watkins
We find the nine bulk--flow and shear moments from the SFI++ survey, as well as for subsamples of group and field galaxies. We constrain the velocity power spectrum shape parameter…
